resilient sealing portion and an attachlng Patented Nov. 17, 1931 UNITEDSTATES PATENT OFFICE MAURICE E. BOSLEY, OF CHICAGO, ILLINOIS, ASSIGNOIR.TO THE D. W. BOSLEY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OFILLINOIS MACHINE FOR AND METHOD OF FORMING WEATHER STRIPPING Applicationfiled February 8, 1928. Serial No. 252,926.

My invention relates in general to weatherstrip making machines and hasmore particular reference to a machine for forming a Weatherstrip byassembling a folded metal strip upon the edge of a resilientWeatherstrip portion and includes a mechanism for automatically cuttingoff the formed Weatherstrip at predetermined intervals as it is formed.

\Veatherstripping comprises a resilient strip of material adapted fordisposal between the cooperating surfaces of movable closures, such aswindows and doors, in order to tightly seal the intermediate crackbetween the closure members when the same are The strip comprises aflange, and the quality of the strip depends in large measure upon theuniformity of the assembled article.

Weatherstripping having an attaching flange formed of a folded metalstrip has great utility for the reason that the metal edge may bearranged in close engagement upon the surface to which the Weatherstripis 1 attached, and tends to hold the resilient weatherstrip portionsmore securely in engaged position. The use of a metal edging alsoeliminates the necessity of securing the Weatherstrip edging to theresilient portion by means of stitching or seaming as is necessary whena Weatherstrip is formed with a fabric attaching flange, the metal stripcomprising the attaching flange being adapted to maintain its assembledposition when once clamped upon the resilient Weatherstrip portionwithout being otherwise secured thereto. The principal object of theinvention is the provision of a Weatherstrip forming machine metal stripand having novel means for adjusting the rolls.

Another important object is the provision of improved means forassembling the folded metal edge and the resilient portions of aweatherstri Another important object is the provision of improved meansfor securing co-operating Weatherstrip portions together.

Another important object is the provision of a Weatherstrip cuttingmechanism adapted to automatically cut the formed Weatherstrip intopredetern'iined lengths as it emerges from the forming rolls of themachine.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

To illustrate my invention I have shown on the drawings a Weatherstripforming and cutting machine com rising a device 11ineluding a plurality0 pairs of co-operating rollers adapted to engage a strip of metalsuccessively and to fold it into a substantially V-shaped strip, anassem ly device 12, including a pair of co-operating rollers, adapted toreceive the folded metal strip from the device 11 and to receive aresilient weatherstrip portion from any convenient source and to securethe two portions together, the portions being assembled and passedbetween the rollers which clamp the V-shaped strip into lockingengagement upon an edge of the resilient Weatherstrip portion, and adevrce 13 adapted to cut the formed Weatherstrip into sections ofpredetermined length.

The strip folding mechanism 11 comprises a supporting base 21 whichprovides a support for cooperating pairs. of strip folding rollers 22and 22. 23 and 23, 24 and 24, and 25 and 25, and a housing 21' forsuitable gear mechanisms for driving the strip folding rollers. Therollers 22, 23, 24 and 25 are suitably mounted upon the upper ends ofvertical shafts 31, which are supported in alignment being suitablyjournalled in the top of the housing 21' and in support ng cross members32 disposed within the housing 21', and the cooperating rollers 22, 23,24 and 25 are secured to the upper ends of shafts 41 similarlyjournalled in alignment through the top of the supporting base 21 andthrough the cross members '32. Gears 33 are secured to the lower ends ofthe shafts 31 and are interconnected by pinions 34 arranged on stubshafts 35 mounted in the base 21. The interconnected gears and shaftsare driven by a chain 36 which engages a sprocket 36' mounted upon ashaft 31, and as the pinions 34 engage gears 33 of adjacent shafts 31,so that all the shafts 31 rotate in the same direction and at the samespeed. Each shaft 41, at its lower end, carries a gear eaaeee 43 havingdriving engagement with the gear 33 of the cooperating shaft 31, drivingpower being supplied to the shafts 41 from the shafts 31 so that therolls 22, 23, 24, and 25 are all driven at the same speed but in adirection opposite to that of the cooperating rollers 22, 23, 24 and 25.The shafts 41 are rotatably mounted in cylindrical bushings 44 havingeccentric bearing apertures in which the shafts are journalled. Theupper portion of each bushing 44 is journalled in a cylindrical boss 42formed in the top of the base 21, the lower bushing portions extendingdownwardly into the housing 21 and carry ing a worm wheel 46 securedthereto by means of a set screw 47. The worm wheel 46 has threadedengagement with a worm gear 43 mounted on a shaft 49 suitably journalledin a bearing 51 arranged in the side of the base 21. The outer end ofthe shaft 49 is provided with a hand wheel 52. Rotation of the handwheel rotates the bushing 44, the eccentricity of the bushing causingthe upper end of the shaft 41 to move eccentrically thus varying thespacing between the upper ends of the shafts 41 and 31, thus providingmeans for adjustably spacing the cooperating rollers.

Power is delivered to each of the devices 11, 12 and 13 through a mainshaft 61 which may be driven in any convenient manner. such as by abelted fly wheel 62. The shaft 61 is journalled in bushings 63 which areformed in supporting uprights 64 bolted to a projecting portion 65 ofthe base 21 of the metal strip bending device 11. The shaft (11 isprovided with a bevel gear 66 arranged to engage a cooperating gear (37mounted on a stub shaft 68 suitably journalled in a hearing supportedbetween the uprights 64. The shaft 68 carries a sprovket at its lowerend. This sprocket engages and drives the endless chain 36 which in turndrives the rollers of the metal strip bending device 11.

The Weatherstrip is formed from a resilient portion 14 and a metal strip15, a roll 16 of which is mounted upon a convenient pedestal 17 situatedadjacent the strip folding mechanism 11. The strip is fed from the roll16 between the cooperating rollers 22 and 22' which have peripheralsurfaces adapted to offset the strip at 15' substantially 11 shown inFig. 9.

After leaving the rollers 22 and 22fthe so ofi'set strip passes betweenrollers 23 and 23 which fold the strip longitudinally substantiallyalong a line of bend 18 and provide a longitudinal groove 19substantially midwa between the line of bend 18. and one edge of thestrip. as shown in Fig. 10. The s1l("'e(ding rollers 24 and 24'. and 25and 25 fold the strip still further along the line of bend 18 andprovide the substantially V-shaped formation illustrated in Fig. 12. Thestri p 15 is guided between successive rollers by rollers 71 and 72.

means of guides 26 and 27 mounted in support brackets 28. The guides 26,being arranged to guide. the stripon either side of the first pair ofrollers 22 and 22 while the strip is in a substantially fiat condition,are adapted for vertical adjustment in the support brackets 28 by meansof hand Wheels 29 to provide control of the relative position of thestrip in the rollers 22 and 22, so that the offset at 15' may be formedin the strip at any desired distance from an edge thereof thus toaccommodate strips 15 of various widths in the machine.

The Weatherstrip assembling and forming device 12 comprises cooperatingupper and lower rollers 71 and 72. The lower roller 72 is mounteddirectly on and driven by the main shaft 61, the upper roller 71 beingmounted upon a stub shaft 73 journalled ec- 'entrically in a shaft 74which is itself rotatably mounted in bearings 63 formed in the uprights64. The shaft 74 carries a worm wheel 76 secured thereon by means of akey 75 and a set screw 77. The worm wheel engages and is driven by aworm gear 78 retatably supported from the forward upright 64 androtation of which by a hand wheel 79 provides a means for adjustablyspacing the rollers 71 and 72 similar to the adjustment provided betweenthe cooperating rollers of the device 11. The shaft 61 carries a gear 81having driving engagement with a cooperating gear 82 mounted upon theshaft 73 to provide for driving the roller 71.

A table 83 comprising a metal sheet is arranged on both sides of therollers and is disposed in a plane substantially level with the upperedge of the lower; roller 72. The table engages the front upright 64 andis supported from the base 21 of the device 11 by means of a strut 84and provides a platform for Weatherstrip assembling devices which areadapted to engage, support and feed the Weatherstrip portions betweenthe The folded strip 15 is delivered from the rollers 24 and 25 of thestrip folding device 11 to a guide 85 which comprises a rectangularblock of metal having a V-shaped groove formed in an edge thereof. Theguide 85 is secured to the table 83 by means of wing nuts 86 and bolts87 which engage the table and pass through slotted portions of the guide85. Set screws 88 mounted in offset portions 88 of the table )I'OYltlGmeans for a curatel ad'ustin the position of the guide with respect tothe table and in alignment with the rollers 71 and 72. A finger 89 issecured to the table 83 and has a tip disposed in the groove of theguide 85 in order to maintain the strip 15 in position in the groove asit slides therein to the rolls 71 and 72, as clearly shown in Fig. 13.

indicated by the reference numeral 14 is fed into the assembly machine12 through a guide 92 mounted upon the table 83 ad ac-ent the finger 89.The guide 92 comprises a folded strip of sheet metal mounted on a pivotpin 93. A set screw 94 having engagement with the guide 92 at a pointspaced from the pivot 93 has threadingengagement with a support 95 andis arranged to adjust the position of the feeding end of theguide. Theresilient portion 14 is fed through the guide 92 and engages the foldedstrip 15. Thus assembled, the portions are passed together between therollers 71 and 72 which engage the folded metal portion and clampittightly about the enfolded edge of the resilient Weatherstrip portion14.

The periphery of the upper roller 71 is formed with an offset shoulderportion 101, and a peripheral groove 102 is formed in this shoulder. Thelower roller 72 overlaps the upper roller and is provided with a flange103 at the overlapped edge. A plurality of spaced channels 104 areformed through the body of the roller 72 and parallel with the axisthereof. Radial apertures 105 are formed between the channels 104 andthe periphery of the roller and register with the groove 102 formed inthe shoulder of the upper roller. These apertures 105 are each adaptedto carry a punch 106 which is held in engaged position by means of a setscrew 107. \Vhen in active position, the point of the punch 106protrudes from the periphery of the roller 72. The punches may berendered inoperative by loosening the set screws 107 sliding the puncheslongitudinally in the aperture 105'until the points of the punch liebeneath the peripheral surface of the roller. The'rollers 71 and 72 aresecured to the ends of their respective shafts by means of keys 71 and72 and screws 91 taking longitudinally into the shafts 73 and 61respectively and engaging the rollers by means of washers 91. The foldedmetal strip 15 is engaged and compressed between the shoulder 101 of theupper roller and the surface of the lower roller 72, and the punches106, being spaced about the periphery of the lower roller, engage thestrip at intervals and pierce a portion 106' of the metal into theresilient Weatherstrip portion lying between the arms of the foldedmetal strip 15. The flange 103 on the lower roller provides a guide sothat the weatherstrip may pass between the rollers with the groove 19opposite the punches in order that the deformation may be produced atthe groove. This deformation of the metal strip secures the Weatherstripparts in engaged relationship and the Weatherstripping emerges frombetween the rollers 71 and 7:2 as a finished product. A guide 108similar to the guide 85 except that the groove therein is adapted toengage the finished weatherstrip instead of the intermediate V-shaped bya hand wheel 171.

edge stri 15, is secured upon the table 83 on the side of the rollersopposite from the guide 85 and guides the finished Weatherstrip awayfrom the rolls 71 and 72.

After passing from the rollers 71 and 72, the completely formedWeatherstrip passes over an intermediate supporting table 109, arrangedas a continuation of the table portion 83 and supported in position uponan upright member 110, which carries the weatherstrip from the formingdevice 12 to the Weatherstrip cutting device 13. The cutting device 13comprises a pair of cooperating rollers 111 and 112 mounted on spacedshafts 113 and 114 suitably journalled in bearings supported in spacedpedestals 163 mounted on a supporting base 124. Each roller is providedwith a radial slot 115 extending across the face of the roller parallelwith the axis thereof. This slot is adapted to provide a seat for aknife blade 116 having a body portion engageable within the slot and anedge portion arranged to project from the peripheral surface of theroller. A portion of the roller parallel with and adjacent to the slot115 is cut away as at 117 leaving a shoulder 118 between the cutoutportion 117 and the slot 115. The knife portion 116 is held removably inplace in the slot 115 by means of a stud 119 having threaded engagementthrough the shoulder portion 118 and engaging the knife portion tosecure it in the slot. The adjacent portions of the peripheries of therollers 111 and 112 are spaced apart a distance sufficient to allow thefinished Weatherstrip to slide between the roll- (-rs when in thenormally inoperative or nonutting position shown in Fig. 20 of thedrawings. The shafts 113 and 114 carry cooprrating gears 159 and 161 andare arranged to rotate at the same speed in opposite directions so thatthe knife edges 116 may have registering cutting engagement asillustrated in Fig. 21 of the drawings upon rotation of the rollers. Thelower shaft 114 is supported at both ends in bearings 163 suitablymounted on the spaced pedestals 163. The upper shaft 113 is mounted inbearings 158 slidably mounted upon the spaced pedestals 163' andadjustable in one case by means of a set screw 169 supported from theforward pedestal. 163' by the bracket 169, and in the other case bymeans of a threaded shank 171 supported in a bracket 172 and controlledThe shank 171 engages a pin 172' in the bearing 158 and thus providesmeans for adjusting the same. The rollers 111 and 112 normally remainstationary in the position shown in Fig. 20 and are actuatedperiodically by a mechanism comprising a plurality of gears and pinions,which will now be more fully described. These gears are driven from asprocket 121 mounted upon a shaft 122 suitably supported in bearings 123arranged on the supporting base 124. The sprocket 121 is driven by achain 125 which passes over a sprocket 126 mounted upon the main driveshaft 61 heretofore mentioned in connection with the devices 11 and 12.

A pinion 127 is mounted upon the shaft 122 and drives a gear 128 mountedon a shaft 129 which is suitably supported in pedestal bearings 131mounted upon the base 124. The shaft 129 also carries a inion 132 whichhas driving engagement wit a gear 133 rotatably mounted upon a pin 134.This pin is mounted through an aperture 139 formed in an arm 135 whichis pivotally mounted upon the shaft- 129 by means of a bearing 136formed at one end of the arm 135. A quadrant 137 having a curved slot138 formed therein is arranged at the free end of the arm 135. The armis adjustably secured to an upright 142 by means of a nut and bolt 141which engages through the slot 138 and an aperture in the upright. Theupright is suitably mounted upon the base 124. The bolt 141 slidinglyengages in the slot 138, and, upon tightening the nut, the upright 142and the arm 135 may be adjustably fastened together to provide forarranging the arm in various angular relationship with respect to theshaft 129. The gear 133 engages a removable gear 143 mounted upon theend of a shaft 144 which in turn is rotatably mounted in a pedestalbearing 145 supported from the base 124, the gear 143 being held inplace by means of a bolt 146 engaging the gear 143 and taking into theend of the shaft 144. The adjustable quadrant 137 provides means wherebygears 143 of various size may be mounted upon the shaft 144 to provide ameans for driving the shaft at a plurality of desired speeds. Amutilated pinion 147 is mounted upon the end of the shaft 144 oppositethe gear 143. This pinion 147 comprises a hub 148 providing engagementwith the shaft 144, a web and rim 149, parts of which are cut away alonga line 151. Gear teeth 152 are formed along substantially one half ofthe remaining rim of the mutilated pinion, the other half of the rimremaining blank. A pinion 153 mounted on a shaft 154 supported insuitable bearings 155 mounted in pedestals 155' supported from the base124 is arranged to be driven by the teeth 152 as the mutilated gear 147is rotated. The shaft 154 carries a gear 156 which is arranged to engagea pinion 157 mounted on the shaft 113 and hence to rotate the cuttingrollers 111 and 112.

A guide 164 formed of sheet metal is sup ported from the base 124 bymeans of an upright 165 and is arranged to conduct the formedWeatherstrip from the intermediate platform 109 to the rollers 111 and112. A receiving table 166 and a Weatherstrip guide 167 supported fromthe base 124 by means of an upright supporting member 168 are arrangedopposite the rollers to support and guii'le the Weatherstrip afterpassing through the rollers.

During the inactive period, the operating mechanism of the Weatherstripcutting rolls is locked in inoperative position by means of a lever arm173 pivotally mounted on a pin 174, which is supported from a bracket174" mounted on the bearing pedestal 155. An offset portion 175 at oneend of the lever arm 173 is normally urged by a spring 178, attached atone end to a pin 179 in the pedestal 155 andiat the other to the leverarm, into engagementin a slot 177 formed in the rim of the gear 156,which is then looked in place. The opposite end 176 of the lever 173 isprovided with an oppositely extending offset portionwhieh engages asideof the rim 149 of the mutilated pinion 147. The rim 149 during rotationof the pinion slides along the portion 176 of the lever 173 and isoffset as at 181 providing a shoulder along the rim which is adapted toengage and lift the offsetportion I 176 of the lever and to rot-ate thelever against the tension of the spring 178 and disengage the portion176 from the slot 177 of the gear 156 when the mutilated pinion engagesthe pinion 153; that is to say, when the strip cutting mechanism is inoperation. When driving engagementbetween the mutilated pinion .147 andthe pinion 153 ceases, the offset portion 175 of the lever 173 ridesupon the rim of the gear until it engages the slotted portion 177, theinertia of the mechanism causing rotation of the parts after drivingengagement between the mutilated pinion and the pinion 153 has ceased.

In operation the finished Weatherstrip, guided by the member 164, slidesbetween the rollers 111 and 112 until a predetermined length has passedthrough, at which time the mutilated gear wheel 147, which is rotatedcontinuously and at uniform speed from the main drive shaft 61 throughthe chain 125 and the train of pinions and gears 127, 128, 132, 133 and143, reaches a position in which the teeth 152 thereof engage and drivethe pinion 153 which, up to this time, has been locked in a stationaryposition by the catch member 175. The pinion 153 in turn drives therollers 111 and 112 and the knives 116 come into registering engagementon opposite sides of the weatherstrip and sever the same,

as illustrated in Fig. 21 of the drawings, the cut ends 185 of theWeatherstrip assuming a conformation illustrated in Fig. 22 of the d'awings and providing a neat severed Weatherstrip end.

The cut length of the Weatherstrip depends upon the frequency with whichthe mutilated pinion has driving engagement with the pinion 153. This isdetermined by the gear ratio between the removable gear 143 and the gear133. The driving gear 133, being rotatable about the pin 134 is adaptedto have driving engagement with gears 143 of various sizes and should agreater strip length be desired, a gear having a lar er diameter issubstituted upon the shaft 144 1n place of the gear 143.

The number of Weatherstrip lengths cut by the cutting mechanism isrecorded by a counter 182 conveniently supported on a bearing pedestal163 ad acent the free endof the shaft 113. The counter 182 has an arm183 extending across the end of the, shaft. A plate 184 carrying a pin185 is secured to the end of the shaft and rotates therewith, the pin185 engaging the actuating lever 183 of the counter 182 and moving itthrough a counting cycle once per revolution of the shaft 113. Since therollers 111 and 112 rotate but once in cutting the strip, the counter,being arranged to count the rotations of the shaft, records the numberof cut lengths of Weatherstrip produced b the machine.

It is thought that this invention and many of its attendant advantageswill be under stood from the foregoing description, and it will beapparent that many changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.
